Utah County Map: All 29 Counties
The State of Utah is partitioned into 29 counties governed under Article XI of the 1896 Utah Constitution. Defined by the soaring Wasatch Range and the Colorado Plateau, Utah displays extreme demographic clustering: over 80% of the state's population resides along the narrow Wasatch Front urban corridor, while vast southern and eastern canyonland counties manage world-famous national parks amidst 67% federal public land ownership.

How Local Government Operates in Utah: Commission Form & Optional Council-Executive Charters
Most Utah counties are governed by a 3-member Board of County Commissioners. Under Title 17 of the Utah Code, counties may adopt optional forms: Salt Lake County operates under an elected County Mayor and 9-member County Council, while Summit and Cache utilize Council-Manager formats.
The Wasatch Front vs. The Mighty 5 Canyonlands
Utah's 29 counties encompass one of the most starkly clustered demographic maps in the United States.
Over 2.6 million of Utah's 3.3 million residents live along the Wasatch Front, a continuous 120-mile urban corridor spanning Salt Lake, Utah, Davis, and Weber counties. Wedged between the Wasatch Mountains and the Great Salt Lake, this tech and industrial corridor houses the state's premier universities (BYU in Utah County and the University of Utah in Salt Lake).
In radical contrast, the canyonland counties of southern and eastern Utah—San Juan, Grand, Garfield, Kane, Wayne, and Emery—span thousands of square miles of red rock plateaus, labyrinthine slot canyons, and the "Mighty 5" national parks (Zion, Bryce Canyon, Capitol Reef, Arches, Canyonlands).
San Juan County in the Four Corners region covers 7,821 square miles—larger than Connecticut and Rhode Island combined. Encompassing Bears Ears National Monument and the northern Navajo Nation, San Juan County features an Indigenous majority population, electing the first Navajo-majority county commission in Utah history.
At 7,821 square miles, San Juan County is the largest county by land area in Utah and the 24th largest in the United States, bordering Arizona, Colorado, and New Mexico at the Four Corners.
Title 17 County Charters & The Salt Lake Metro Reformation
Utah law provides flexible county government structures to accommodate explosive metropolitan growth.
Under Utah Code Annotated Title 17, Chapter 52a, counties may choose between five optional forms of government: the traditional 3-member commission, expanded commission, executive-council, council-manager, or council-administrative officer.
In 1998, Salt Lake County voters approved an executive-council charter, establishing an elected County Mayor as the chief administrative officer and a 9-member County Council (six elected by district and three at-large). This structure modernizes oversight over Salt Lake County Parks, regional watershed management, and the Salt Palace Convention Center.
County commissioners in rural Utah manage substantial public-lands interface issues, including federal Payments in Lieu of Taxes (PILT), grazing permits on BLM rangelands, and water storage in the Colorado River basin.
Utah Code Title 17 gives county voters the power to initiate charter reform petitions, allowing rapidly growing counties like Summit and Cache to adopt professional manager systems.

Data Sources & FIPS Codes
Utah uses state FIPS code 49; each county adds a three-digit code to form the five-digit FIPS (now INCITS 31) identifiers in the table. Populations are 2020 Census counts and land areas come from the Census Gazetteer. The map above is drawn from the Census Bureau's generalized 2017 cartographic boundary file (1:10,000,000), so it suits overview and printing, not parcel-level or legal boundary questions; for those, check the local assessor or GIS office.
